An overview of biodiesel soil pollution: Data based on cytotoxicity and genotoxicity assessments

► Biodiesel is designated a green fuel due to its contribution in air pollution reduction. ► Biodiesel impacts should also be estimate in other biotic systems, e.g. soil. ► Toxicological investigations were performed in soils contaminated with biodiesel and their diesel blends. ► Soils polluted with biodiesel and their diesel blends showed genotoxic/mutagenic effects. ► Designation of biodiesel as a green fuel should be carefully reviewed to assure environmental quality.
